In my form settings, I have a warning box that says:
The plugin requires a writeable temporary directory for file uploading. You can set a custom temporary directory path in your wp-config.php file by using the code define(“WP_TEMP_DIR”, “/path/to/tmp/dir”);
So I created a directory called wp/temp (wp is the root) and added same to config.php
I’m having the same issue. I have a temp directory under WP-Content, the folder has full permissions, and the setting in WordPress > Quform > Settings says:
Temporary Directory /wp-content/temp
But it still is showing a negative sign and giving the same error posted above.
